Document Summary
Instructions for part i: the rst six (6) pages are short answer, you don"t need to show work, partial credit will be rare, (10 pts. ) Assume that any letter other than t is a constant. (a) d dt (cid:18)p ert(cid:19) = (b) d dt (cid:18)h0 + v0t + The height of an object is a function of time, h(t), with h in meters and t in seconds. You will not be given a formula or any numerical data for h. however, a person who does know the formula for h has gured out a formula for average velocity on the interval [0. 7, u]. 4 sin(2u) 4 sin(1. 4) u 0. 7 (a) complete the following table of average velocities. Each answer should be accurate to 2 decimal places and must include correct units. [0. 7, 0. 72] (b) estimate the velocity of the object at the instant t = 0. 7 seconds.
